Be itknownthat I, JOHN T. SCHAAEF, a

Washington, inv the District of Columbia,, have invented certain new" and usefullmmovements in Operating Attachments for Keyboard-Machines, of which the following g -'1s a description, reference being had to the accompanying. drawing. and to the letters; and figuresof reference marked thereon. ,My invention relates to, typewrltmg and,

other key;ac t uate d nfachin'esand has for its object to provide a device capable of being.

readily attached to a typewriting or other; key-actuated machlne,provided with means;

-for operating the key levers of the type- I -writing or other machine by power mecha-i nism. 4 'Typewriting' machines-as ordinarily constructed and-fused are arranged tobe oper-- ated to efi'ect the printing by'the impact of} the finger of the operator on the.finger'keys. The force necessary to cause the-typebar to;

strike the platen, especially when it is desired to make-carbon copies, is considerable and irhordertolessen the strain uponfthe: strength of the operatonvariousmachmes have been devised in which electrioor other power is used to efiect the printing, the keys being used only toselect the typebar to be operated and set the power mechanism in operation or connect-it with the typebar sel'ected so' as to efiect its operation. Such machines-have not :as yet gone into exten-".

sive use for the reason that they have been, as heretofore ofiered on the market, morecumbersome'and complicated than the ordinary typewriting'machine, as well as more expensive, and because ersons owningand using typewriting mach nes of the'ordinary kind have not been-willing to discard their old and fairly satisfactory machines to purchase a new machine which however. satisfactory when operated by electric or other power, would become useless if the of current or other power failed.

By the use of the device of mypres'ent invention, an ordinary typewri'ting machine ,such as is in general use may be readily converted into a power-operated mach1ne,

without displacing or otherwise changing an of its essential features and without! a ecting its usefulness as an ordinary typewriting machine upon the removal of the Specification-'0 Letter-shunt. Paeeg tegli)ec.10,19 12;j Application and me u gaieoi. Serial mar appearance.

The key-levers are pivoted at their rear ends as usual and are held normally in elevated position by the usual springs 11.

.So far'as thus described,the machine doesnot differ from the usual form of Remington.

' the push-,fingers-and at the other end to the lever serve to hold the push fingers in the position in which they are shown in Figs. 2

typewritipg machine in general'use.

The main operating parts of my attachment are carried by a plate 12 adapted to top-plate to hold the plate against the front parts 0 uprights The plate 12 s preferably p ovidcd' on one side with a rearward extension is tachment imposition, rests on theicross extension 14 zit-"right angles to the main' .portion of .the plate, this extension, when the attachment is iii-position, lying along one The rear eudof this side of the machine.

preferably hcnt outward to "formalug15.

At its lower end the plate 12 is provided with an angle plate 16 which when the athar 17 of the-typewriting machine and is held from forward movement by'istops '16 secured to the plate 16 and preferably pro-j vided with adpistable screws which rest' against the rear edge of the'cross-bar 1:7. On the upperface of the angle plate 16 is secured a. bar 18 haringa series of slots 19 formed therein corresponding in number to the key-levers In these slots 19 are pivoted angle or bell-crank levers 20, the horizontal members of these angle levers extending rearward and each having its end In engagement The with a recess or notch 21 of a slide 22. slides are carried in slots 23 formed in a bar 24 which extends across the machine an'd is'secured at its ends to the bar 18 by means of braces 18, the slides being free to move vertically in thc'slots. The slots 23 are so arranged that the slides 22 will each: be di-Y 'rectly above and in line with one of the keylevers (5. In order to prevent the'se slides from dropping out'of their slots when the attachment is removed from the machine,

. they may be cut away' on their forwardfaces so as to le'ai'estops 25, 26, and a: rod 27 is located between these stops as shown.

To'the upper end of the vertical. arm of the lever 20 is pivoted afo'rwardly extend ing push-finger 28, provided on its upper edge with a forward sh'gul der 29 and an upward extension 30 terminating atits for-.

'ment'of the forward end. of the push-finger Each .of the a hereinafter; described. The push-fingers 66'- wh'en in' initial position rest on the upper "ffaceof a bar 32'car ried bythe plate 19 and i which extends across the machine and is preferably provided on itsuppcr face with a covering '33 of felt or other soft material. The push-fingers 'are cut away on their lower faces to form' shoulders 34, the faces of which extend forward; at an acute angle as shown. Springs 35 secured at one end to and 3.

It will be clear from the above description that force applied to the push-finger 28' to drive it rearward will, through the lever 20, move the slide .22 downward to depress the key-lever 6, and through its connection with the typebar will cause the latter to be oper-' ated, the depression of the key-lever also,

through the universal bar v p 10, releasing the carrlage'fcedf For the purpose ofdriving the push-fin-- vi get-rearward, I provide motor frame 36.

1 carried .byarms 37," pivoted in lugs 38,

formed on or'sccured to the plate .12, and arranged tob'e operated by as'uitable motor 39 -(here-sh0wn" anfelec't'ror'nagnet) carried 'bythe'plate 12. Ashere shown the magnet 39 is carried byj-the extension 14of the plate 12 and is secured at-its-rear end-to the-lug 1-5. The magnet 1s arranged-ma normally open circuit which .is arrangedtobe momem tarily closed by, mechanism hereinafter de-" scribed. On the front of the plate '12 'is/secur'd an angle plate 40 in which are pivoted'the kevlevers 41 of. auxiliary finger 'kevs 42. In the constructionlshown the angle plate 40 has 'aYIependingflange 43 in 'front and a.

.depcndiz'u flange 44- in rear and is provided on itsfundcr sidebctween the fiane'eswith a str1p of felt or other softmaterial45. The

flanges 43 and 44 are slotted "to receive the rear ends of the key-levers 41, the slots in the front flange extending, nearly to the lower face of. the plate, while the slots in the rear flange terminate a sufficient distance below the lower face of the plate topermit the ends of the slots 'to serve as the fulcra for the key-levers 41, which arenotchedon their upper faces at 46. In order to prevent accidental displacement. of these key-levers, a bar carried by I belts or screws 48 extends across the machine below the rear ends of the key levers 41, the distance of this bar below the keylevers being such that the key-levers are permitted free movement The. slots in the flanges 43 and 44 guide the'key-levers 41. in their vertical. movement and prevent any lateral movement.

-Through the bar 32 are formed slots in line with and corresponding in number to the leVersQOQand infeach' of these slots is pivoted a lever 50 on the rear end of which 25 common. fulcrum and by suitablyfbeiiding theurpr ends of the bars orf-rod s -.53 as *the key lever 41. As the key-levers'41 are necessarilyo'f dilferent length in order that thefinger keys carried by them may correspond in position with the keys 7 of the ordi'nary ke -bo ard, thenotches 54 will be so, 'positione that the depression of a key42,

whatever the length of itskey-lever, will de press its lever 50 the same ,distance. I This could be provided for by pivoting the keylevers 41st different points, but I prefer to provide for-overcoming the difference .in leverage by. arranging the notches E of the several levers at difierent distances from the .Above the push-fingers 28 is a contact:

frame 55'extending across the machine,.carried by arms 5": pivoted in lugs formed on or secured to the rear of the plate 12. An arm '59 carried by the. contact frame carries a movable cOntactGQ' IPi Hit with the cur-' rent supply and adapted, 1 when, the. contact frame is lifted,to' be -brought against a fixed contact -61 carried by the plate- 12 and in circuit with the magnetfto clo'se'lthe circuit and thus actuate the magnet swing the motor frame A spring 62 secured at one endto the plate 12' and atthe other end toilthe arm 59, serves to-separate the; contacts 60 and 61' and to return the contact frame to'its initial-position; 4 h When'the attachment is in position andthe current turned on, the depression of any one-of the auxiliary keys 42 will throughthe bar or rod 53, depress the forward end of its lever 50, raising its rear end and through the pivoted arm 51, raising the push finger 28 until the shoulder 29 is in line with the motor frame 36. As the-push fingeris' thus raised, its upward extension 30 raises the contact irame '55 and causes the arm 5915i) bring the oontact-60 against the fixed contact 61, closing the-circuit of. the-magnet,-

' which is thus actuated to. swingathe motor frame rearward. against the ,shoulder 29, forcing the push finger rearward and," through the lever and slide 22, causing the key-leverlo'be depressed to operate the tvpebar As the push finger 28 is thus moved rearward, the shoulder-30 of the upwardfextensioniiflpasses totherea-r of the drop under the action of the spring 62: thus a. M i fe' separating the contacts and 61 and breakingthe circuit of the magnet, At the. same time the shoulder 34 on'the under side of the push finger passes to the rearbf the upper end of the pivoted arm 51, sothat thc pivoted arm is free to be swung into'vertic-al 1 position by the spring 52. The motor frame, havin' returned to its initial position, the

push nger 28 and lever 20 arereturned to mitialipositions by the return of. the keylever 6 to its initial position under theacticn of the s ring 11, aided blyl' the weight of the type art" As the pus moved ,forwardto its initial position, its

forward and drops till it rests on the felt 33, the shoulder 34 pushing the upper end 'of the arm 51 forward against the force of finger is thus "the'spring 52, until itrests against the rear face of the bar 32, the operating part thus returning to initial position without regard to the release of the auxiliarykey 42, On'

the release of the auxiliary key 42, the

s ring-'52-draws the rear end of the lever 50 ownward and at the same timereleases the upper end of the pivoted arm 51 fromthe shoulder '34 and returns-it to its initial pos' tion. The spring 52also acts to raise the forw d end of lever 50 and through the rod.-

or bar raises the auxiliarykey to initial positionf In order that the space key, when the a't-i I tachlnent in position, may be located in the same relative positioniwith reference to I n J it is preferably p rothe auxiliary key-hoard, which itoccupies relative to the keys 7 ,vi'ded with a removable-bar 70, supported by arms 71 provided with clips'71 by which it may bereadily secured to the space key, flh'el pivots of'the motor frame may be arranged either above the angle plate in which the. auxiliary keys are pivoted, as

shown in Fig. 2, or below the plate, as shown On the extension 14, below the magnet, is preferablyarrafnged a rheostat 74, for regulating the-forcehf the current; and the extension alsocarries contact plu s 75- to which the wires from the source o current may be attached and may alsobe provided with sockets or clips 76 to receive a removable fuse 77.

- In the construction shown in 1 and.
